Answer 1

Protista.

Question 2

Where can you find protists and what tool do you need to see them?

Answer 2

A pond. A microscope.

Question 3

What is the key difference between protists and monerans?

Answer 3

Monerans = no distinct nucleus (aka) prokaryote, found nearly everywhere, very small - need the strongest microscopes

Protists = distinct nucleus (aka) eukaryote, mostly aquatic, larger - need simple microscopes

Question 4

Define prokaryote and eukaryote.

Answer 4

Prokaryote - an organism that has no distinct nucleus

Eukaryote - an organism that has a distinct nucleus

Question 5

Which class of protists is animal-like and how do they get their food?

Answer 5

Protozoa. They get their food by eating other small protists.

Question 6

Which class of protists is plant-like and how do they get their food?

Answer 6

Algae. They get their food by photosynthesis. (aka sunlight)

Question 7

What are the key differences between protozoa and algae?

Answer 7

Protozoa - Animal-like, take in food, no chloroplasts, no cell wall

Algae - Plant-like, make food by photosynthesis, chloroplast present, cell wall present

Question 8

What are the three classes of protozoa based on movement?

Answer 8

Sarcodines- cell oozes along making new pseudopodia (false feet)

Ciliates- tiny hair-like structures (cilia) that beat

Flagellates- use a whip-like flagellum to move

Question 9

What class of protozoa is based on reproduction?

Answer 9

sporozoa. (???)

Answer 13

Diseases and contamination.

Question 14

How are algae classified?

By pigment and cell number.

Question 15

Why are all algae not green?

Answer 15

Because their pigment are different colors.

Question 16

What are dinoflagellates and diatoms?

Answer 16

Dinoflagellates - large amounts of red pigment, contain 2 flagella

Question 17

What is a euglena and what do they look like?

Answer 17

Euglena - green with a single flagellum, can make or eat food, contain an eyespot to detect light

Question 21

What is an algae colony?

Answer 21

A colony is a group of algae cells living together that may or may not develop complex structures.

Question 22

What are some helpful interactions between algae and man?

Answer 22

oxygen production, food, chemicals like agar and thickeners, polishing materials.

Question 23

What are some harmful interactions of algae and man?

Answer 23

red tides - poisons fish and animals, shell fish poisoning.

Question 24

Why are fungi eukaryotes?

Answer 24

Because they have a nucleus.

Question 25

How do fungi get their food and what is a decomposer?

Answer 25

Fungi get their food by absorbing nutrients in the ground a decomposer is something that breaks down the rotting things around them.

Question 26

What are spores?

Answer 26

Spores are the start of most fungi.

Question 27

What are hyphae?

Answer 27

Bodies of many-celed fungi are formed from many branching, thread-like filaments called hyphae.
